Applications

Built for enterprise access, campus, telecom edge and industrial network environments, this SFP module carries 1.25Gbps over MMF up to 550m over OM2 MMF per link. The Duplex LC interface and 850nm optics match the standard cabling plant used in modern data halls, so existing trunks can be reused. Compatibility with Cisco systems is verified in our own test lab before shipment, so the unit works out of the box as an equivalent of GLC-SX-MMD.

Standards and Compatibility

This product is designed and tested to comply with IEEE 802.3z, SFF-8472, FC-PI, SFP MSA (INF-8074i) Compliant. It is interoperable with Cisco equipment and serves as a direct equivalent to the Cisco part number GLC-SX-MMD.

Ordering Information

Our part number for this module is SFP1G-SX-85-I. When ordering, just let us know the quantity and whether you need the compatibility coding for a particular switch brand; labeling and packaging can also follow your channel requirements.

OEM and Custom Orders

We have manufactured fiber optic connectivity products since 1995 and run our own production lines in Shenzhen. Beyond the standard catalog we build to order: special cable lengths, custom connector combinations, vendor-specific compatibility coding and private labeling. Send us your requirement and our engineers will quote a practical solution.

Shipping and Lead Time

Standard products are held in stock and usually ship within one to three working days. We dispatch worldwide by DHL, UPS, FedEx, TNT or EMS, and for bulk orders we arrange air or sea freight. Shipments can also be sent collect on your own courier account or delivered to your freight forwarder.

Tested Before Shipment

We do not ship untested stock. Each transceiver and cable is powered up in our test racks, checked for link stability, transmit power, receiver sensitivity and diagnostic readouts, and only then packed for delivery. This factory-level testing is one reason network integrators keep reordering from us year after year.

Package

Products are first packed into blister trays or self-sealed bags and then into cartons. Standard labels and marks are applied by default, and customized packing and labeling are available on request.
